Connecting Spin and Statistics in Quantum Mechanics

We emphasize that there is no spin-statistics connection in nonrelativistic quantum mechanics. In several recent papers, including Phys. Rev. A 67, 042102 (2003) [quant-ph/0207017], quantum mechanics is modified so as to force a spin-statistics connection, but the resulting theory is quite different from standard physics.

Recent experiments searching for violations of the spin-statistics connection and of the symmetrization postulate of quantum mechanics are reviewed. Spectroscopic tests on O 2 and CO 2 molecules are described in detail and it is shown that these should be considered as tests of the spin-statistics connection for the spin-0 oxygen nuclei. The possibility of new experiments to test the spin-statistics connection and the symmetrization postulate is discussed.
